Powering (5V & 3.3V) your Implemented Electronics Projects

Powering (5V & 3.3V) your Implemented Electronics Projects

Hi Link Power Supply

You made something amazing and now it’s time to implement it in your house! But, how do you power it? Most hobbyist electronics run on 5 or 3.3 V so you can’t just plug it into mains power. And unlike while prototyping, batteries can’t be used, as implemented projects need to run for extended periods of time. So, in this post, I will go over some efficient ways to convert mains power into low DC voltages.

Note: Along with mains power, I also suggest setting up a backup battery circuit to use during power cuts. More about that here.
